摘　　要：This paper aims to investigate the effects of recasts and working memory on the acquisition of Korean morphological causatives by advanced Chinese learners of Korean. Participants were randomly assigned to two groups： A experimental group and a control group. The experimental group received intensive recasts during task-based interaction, whereas the control group did not. The effects of recasts were measured by two types of tests： An elicited imitation test, as a measure of implicit knowledge, and an untimed grammaticality judgment test, as a measure of explicit knowledge. The findings are as follows. First, from the pretest to the delayed posttest, recasts facilitated the learners＇ acquisition of causative construction by developing both their implicit and explicit knowledge. Second, the results of delayed posttests showed that recasts were more effective in aiding the development of implicit knowledge than explicit knowledge. Third, working memory was found to be a significant covariate in the facilitative effects of recasts on explicit knowledge; that is, it mediated the development of explicit knowledge via recasts as a significant individual difference factor. The effects of recasts were maintained even when the impact of working memory was controlled. （189 words）本文旨在探讨重铸和工作记忆对汉语为母语的高水平韩语学习者习得韩语使役形态的影响。参与者被随机分配到两个群体:重铸实验组和非重铸组。实验组在基于任务的交互活动中接受密集的重铸,而对照组则没有。重铸的影响由两种类型的测试加以确定:诱发性模拟试验用于测量隐性知识;非计时语法判断测试用于测量显性知识。调查结果如下:首先,从前测到后测,重铸通过发展学习者的隐式和显式知识,促进了学习者对使役结构的习得。其次,后测显示,相对显性知识而言,重铸可更有效促进隐性知识的发展。第三,工作记忆是重铸对显性知识的促进效果中的一个显著变量,也就是说,工作记忆,作为一个显著的个体差异因素,通过重铸间接促进了显性知识的发展知识的发展。即使在工作记忆的影响受控的情况下,重铸的促进效果依然存在。
